Just for general knowledge, I recently installed a 32F on my 54cm Sam with Shimano Deore V-Brakes, plenty of clearance, and zero interference. Can't speak to any other combo, but if you have a 54 Sam with V-brakes, rest assured it will work (some light bending required).
I'm super curious if anyone has mounted a Nitto NR20 to a 700c frame set. Might be one of those situations where you just have to buy and bend.
